Since one of the major problems in sound reinforcement is the choice of system (localized or distributed), we carry out an initial linearization that reduces the problem to a single unknown: the number of sources N.

We'll see later that this conceptual reduction is mathematically equivalent to a transfer that allows all useful quantities to be evaluated from a single variable: the opening angle of the sources at 2000 Hz (see § 1.4 1.4).

The advantage of the initial choice (number of sources) is :
